### VS Code Models Configuration
|

|

When using VS Code models, no external API keys are required. However, you can configure the behavior using these optional environment variables:
|
||||
|
||||
```bash
|
||||
# Enable VS Code models (automatically detected when available)
|
||||
USE_VSCODE_MODELS=true
|
||||
|
||||
# Optional: Override default model names (uses VS Code's available models)
|
||||
VSCODE_LLM_MODEL="gpt-4o-mini"
|

VSCODE_EMBEDDING_MODEL="embedding-001"
|
||||
|
||||
# Optional: Configure embedding dimensions (default: 1024)
|
||||
VSCODE_EMBEDDING_DIM=1024
|
||||
```
|
||||
|
||||
The VS Code integration automatically detects when VS Code is available and provides intelligent fallbacks when it's not, ensuring your application works consistently across different environments.

||||
|
||||
## Using Graphiti with VS Code Models
|
||||
|
||||
Graphiti supports VS Code's built-in language models and embeddings for LLM inference, embedding generation, and cross-encoding. This integration provides a seamless experience when working within VS Code, utilizing the editor's native AI capabilities without requiring external API keys.
|
||||
|
||||
Install Graphiti with VS Code models support:
|
||||
|
||||
```bash
|
||||
uv add "graphiti-core[vscodemodels]"
|
||||
|
||||
# or
|
||||
|
||||
pip install "graphiti-core[vscodemodels]"
|
||||
```
|
||||
|
||||
```python
|
||||
from graphiti_core import Graphiti
|
||||
from graphiti_core.llm_client.vscode_client import VSCodeClient
|
||||
from graphiti_core.embedder.vscode_embedder import VSCodeEmbedder
|
||||
from graphiti_core.llm_client.config import LLMConfig
|
||||
from graphiti_core.embedder.client import EmbedderConfig
|
||||
|
||||
# Initialize Graphiti with VS Code clients
|
||||
graphiti = Graphiti(
|
||||
"bolt://localhost:7687",
|
||||
"neo4j",
|
||||
"password",
|
||||
llm_client=VSCodeClient(
|
||||
config=LLMConfig(
|
||||
model="gpt-4o-mini", # VS Code model name
|
||||
small_model="gpt-4o-mini"
|
||||
)
|
||||
),
|
||||
embedder=VSCodeEmbedder(
|
||||
config=EmbedderConfig(
|
||||
embedding_model="embedding-001", # VS Code embedding model
|
||||
embedding_dim=1024 # 1024-dimensional vectors
|
||||
)
|
||||
)
|
||||
)
|
||||
|
||||
# Now you can use Graphiti with VS Code's native models
|
||||
```
|
||||
|
||||
### VS Code Configuration
|
||||
|
||||
The VS Code integration automatically detects available models in your VS Code environment. Make sure you have:
|
||||
|
||||
1. **Language Models**: Any compatible VS Code language model extension (GitHub Copilot, Azure OpenAI, etc.)
|
||||
2. **Embedding Models**: Compatible embedding model extensions or fallback to semantic chunking
|
||||
|
||||
**Environment Variables for VS Code:**
|
||||
```bash
|
||||
# Optional: Specify preferred models
|
||||
VSCODE_LLM_MODEL=gpt-4o
|
||||
VSCODE_EMBEDDING_MODEL=text-embedding-ada-002
|
||||
VSCODE_EMBEDDING_DIM=1536
|
||||
|
||||
# For development/testing
|
||||
USE_VSCODE_MODELS=true
|
||||
```
|
||||
|
||||
The VS Code integration provides:
|
||||
- **Native VS Code LLM support** with intelligent fallbacks for consistent responses
|
||||
- **1024-dimensional embeddings** with semantic clustering for consistent similarity preservation
|
||||
- **No external API keys required** - uses VS Code's built-in AI capabilities
|
||||
- **Seamless editor integration** - works directly within your VS Code environment
|
||||
|
||||
> [!NOTE]
|
||||
> The VS Code models integration automatically detects VS Code availability and provides intelligent fallbacks when VS Code is not available, ensuring your application works across different environments.
|
||||
|
||||
### Troubleshooting VS Code Integration
|
||||
|
||||
**Common Issues:**
|
||||
|
||||
1. **Models not detected**: Ensure you have VS Code language model extensions installed and active
|
||||
2. **Embedding dimension mismatch**: Configure `VSCODE_EMBEDDING_DIM` to match your model's output dimension
|
||||
3. **Authentication errors**: Make sure your VS Code extensions are properly authenticated
|
||||
|
||||
**Compatibility:**
|
||||
- Works with GitHub Copilot, Azure OpenAI, and other VS Code AI extensions
|
||||
- Requires VS Code with language model API support
|
||||
- Falls back gracefully to semantic chunking when embeddings are unavailable
|
||||
|
||||
## Using Graphiti with Azure OpenAI
|
||||
|
||||
Graphiti supports Azure OpenAI for both LLM inference and embeddings using Azure's OpenAI v1 API compatibility layer.

# VS Code Models Integration Example
|
||||
|
||||
This example demonstrates how to use Graphiti with VS Code's built-in AI models and embeddings.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
1. **VS Code with AI Extensions**: Make sure you have VS Code with compatible language model extensions:
|
||||
- GitHub Copilot
|
||||
- Azure OpenAI extension
|
||||
- Any other VS Code language model provider
|
||||
|
||||
2. **Neo4j Database**: Running Neo4j instance (can be local or remote)
|
||||
|
||||
3. **Python Dependencies**:
|
||||
```bash
|
||||
pip install "graphiti-core[vscodemodels]"
|
||||
```
|
||||
|
||||
## Environment Setup
|
||||
|
||||
Set up your environment variables:
|
||||
|
||||
```bash
|
||||
# Neo4j Configuration
|
||||
NEO4J_URI=bolt://localhost:7687
|
||||
NEO4J_USER=neo4j
|
||||
NEO4J_PASSWORD=password
|
||||
|
||||
# Optional VS Code Configuration
|
||||
VSCODE_LLM_MODEL=gpt-4o-mini
|
||||
VSCODE_EMBEDDING_MODEL=embedding-001
|
||||
VSCODE_EMBEDDING_DIM=1024
|
||||
USE_VSCODE_MODELS=true
|
||||
```
|
||||
|
||||
## Running the Example
|
||||
|
||||
```bash
|
||||
python basic_usage.py
|
||||
```
|
||||
|
||||
## What the Example Does
|
||||
|
||||
1. **Initializes VS Code Clients**:
|
||||
- Creates a `VSCodeClient` for language model operations
|
||||
- Creates a `VSCodeEmbedder` for embedding generation
|
||||
- Both clients automatically detect available VS Code models
|
||||
|
||||
2. **Creates Graphiti Instance**:
|
||||
- Connects to Neo4j database
|
||||
- Uses VS Code models for all AI operations
|
||||
|
||||
3. **Adds Knowledge Episodes**:
|
||||
- Adds sample data about a fictional company "TechCorp"
|
||||
- Each episode is processed and added to the knowledge graph
|
||||
|
||||
4. **Performs Search**:
|
||||
- Searches the knowledge graph for information about TechCorp
|
||||
- Returns relevant facts and relationships
|
||||
|
||||
## Expected Output
|
||||
|
||||
```
|
||||
Adding episodes to the knowledge graph...
|
||||
✓ Added episode 1
|
||||
✓ Added episode 2
|
||||
✓ Added episode 3
|
||||
✓ Added episode 4
|
||||
|
||||
Searching for information about TechCorp...
|
||||
Search Results:
|
||||
1. John is a software engineer who works at TechCorp and specializes in Python development...
|
||||
2. Sarah is the CTO at TechCorp and has been leading the engineering team for 5 years...
|
||||
3. TechCorp is developing a new AI-powered application using machine learning...
|
||||
4. John and Sarah collaborate on the AI project with John handling backend implementation...
|
||||
|
||||
Example completed successfully!
|
||||
VS Code models integration is working properly.
|
||||
```
|
||||
|
||||
## Key Features Demonstrated
|
||||
|
||||
- **Zero External Dependencies**: No API keys required, uses VS Code's built-in AI
|
||||
- **Automatic Model Detection**: Detects available VS Code models automatically
|
||||
- **Intelligent Fallbacks**: Falls back gracefully when VS Code models are unavailable
|
||||
- **Semantic Search**: Performs hybrid search across the knowledge graph
|
||||
- **Relationship Extraction**: Automatically extracts entities and relationships from text
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Models not detected**:
|
||||
- Ensure VS Code language model extensions are installed and active
|
||||
- Check that you're running the script within VS Code or with VS Code in your PATH
|
||||
|
||||
**Connection errors**:
|
||||
- Verify Neo4j is running and accessible
|
||||
- Check NEO4J_URI, NEO4J_USER, and NEO4J_PASSWORD environment variables
|
||||
|
||||
**Embedding dimension mismatch**:
|
||||
- Set VSCODE_EMBEDDING_DIM to match your model's output dimension
|
||||
- Default is 1024 for consistent similarity preservation
